SHOP CASE KNIVESThe Spyderco Police 4 Lightweight in cobalt blue is a modern take on a legendary design, delivering cutting-edge performance in a streamlined, easy-to-carry package. Built for those who demand more from their everyday carry folding knife, this model blends premium materials, thoughtful engineering, and a touch of bold style.
At the core of this impressive folder is a 4.38-inch clip point blade crafted from high-performance CPM SPY27 stainless steel. Developed in collaboration with Crucible Industries, SPY27 offers an exceptional blend of edge retention, corrosion resistance, and toughness. Its fine, plain edge excels at precision slicing, push cuts, and everyday tasks with effortless control. Finished with a clean satin sheen, the blade not only looks refined but is built to tackle demanding jobs with unwavering reliability.
True to Spyderco form, the blade features the brand’s signature round thumb hole for quick, ambidextrous one-handed deployment. Whether you're opening the knife in a rush or finessing it into use during a task, the action is smooth and dependable. It's a manual folder by design, giving you tactile control and confidence every time you use it.
One of the standout features of the Police 4 Lightweight is right in its name—lightweight. Weighing just 4.2 ounces, this knife offers a nearly 10-inch overall length without burdening your pocket. The handle is constructed from FRN (fiberglass-reinforced nylon), a rugged and grippy material that’s both strong and featherlight. The cobalt blue finish adds a bold, contemporary look that sets it apart from standard fare, while the bi-directional texturing ensures a solid, non-slip grip even in wet conditions.
The ergonomics are spot-on. With a 5.64-inch closed length, the handle feels natural in the hand, whether you're wearing gloves or not. The slim .11-inch blade thickness contributes to outstanding slicing performance without adding bulk, and the whole knife feels agile without sacrificing strength.
A four-position pocket clip offers unmatched carry versatility. Whether you prefer tip-up or tip-down, left- or right-handed carry, this knife adapts seamlessly to your setup. It’s fully ambidextrous, making it a perfect choice for anyone, regardless of dominant hand. The open-backed construction also makes cleaning and maintenance a breeze, ensuring your knife stays ready for daily use.
The Spyderco Police 4 Lightweight is more than just a refined tool—it’s a trusted companion for those who take their gear seriously. From first responders to seasoned outdoor adventurers and everyday knife users, this folder delivers outstanding performance with a modern edge.
